Abstract
A sliding contact micro-current combined switch comprises a handle assembly, a slider movably connected with the handle assembly, a contact bridge mounted on the slider, a PCB (printed circuit board) with a circuit conductive contact area, and a shell supporting the PCB and the slider. The contact bridge is in a bend structure. A blistering for connecting a circuit is further reserved at the front end of the contact bridge. The sliding contact micro-current combined switch is simple in structure, plastic deformation and sudden-changing stress of the contact bridge in the whole moving process are omitted, operational hand feel is improved greatly while service life of the contact bridge is prolonged, and the sliding contact micro-current combined switch is widely applicable to the field of combined switches.
Description
Technical field
The utility model relates to a kind of unit switch, relates in particular to a kind of slidingtype and contacts little currents combination switch.
Background technology
We generally comprise left joystick assembly and right joystick assembly with unit switch by common automobile; Left side joystick assembly mainly is combined to form by each part such as rivet of the shell that is used for fixing slide block and socket, the slide block that has trajectory shape, the socket that has built-in conducting strip and contact, the thimble that is used for the top conducting strip, the conducting strip that has the contact, fixed socket and conducting strip; Wherein operation principle is: through the operating grip assembly; Drive corresponding handle assembly internal mechanical structure motion, have the slide block of trajectory shape then, conducting strip is fixed on above the socket of built-in conducting strip and contact through rivet; Thimble is between slide block and conducting strip; When the slide block movement of trajectory shape was arranged, thimble moved up and down according to the shape of track, and conducting strip is in conducting state when fore-set does not push up it; Thimble under the effect of slide block toward conducting strip direction motion, thereby conducting strip is produced plastic deformation and breaks off.When whole motion process realizes circuit turn-on and breaks off; The whole motion of contact is the clapper-type motion mode; There is following defective in this mode: the contact is prone to produce the vibration between the contact when clapper-type contacts, and influences the signals collecting of system, and the clapper-type motion is stopped by foreign material between the contact easily; Cause not conducting of circuit, the precompressed that realizes connecting and disconnecting of the circuit again through plastic deformation own of the elasticity precompressed of the conducting strip of clapper-type motion dependence own at durable back influencing contactor.Be prone to produce the loose contact between the contact.
The utility model content
The purpose of the utility model provides a kind of slidingtype and contacts little currents combination switch, solves the plastic deformation of conventional conductive sheet and causes loose contact, the problem that useful life is short.
The utility model solves the technical scheme that its technical problem adopted: a kind of slidingtype contacts little currents combination switch; Comprise handle assembly,, be installed in the contact bridge on the slide block with the slide block of handle assembly active link; The pcb board that has the circuit turn-on contact area; And supporting the shell of pcb board and slide block, described contact bridge is the contact bridge of bending structure, also is provided with the convex closure that is used to connect circuit at the front end of contact bridge.
Be the movement locus of better controlled slide block, housing is provided with the gathering sill of guide shoe motion.
For guaranteeing that contact bridge can well overlap with the circuit turn-on contact area on the pcb board, described contact bridge leading portion is split up into 3, all has convex closure on each sheet.
The beneficial effect of the utility model: the bending structure through contact bridge self and be arranged on the convex closure structure of contact bridge end; Can make contact bridge when doing horizontal translation with slide block; Road conducting contact area overlap joint on smooth-going and the pcb board or separate; Contact bridge is distortion not, the damage of having avoided the contact bridge distortion to cause, the useful life of having improved contact bridge.Gathering sill on the housing can guarantee that slide block moves according to the route of design, realizes the circuit turn-on contact area overlap joint on contact bridge and the pcb board.3 convex closures are set on the contact bridge, can guarantee the circuit turn-on contact area overlap joint on contact bridge and the pcb board.This contact bridge is simple in structure, and contact is good.
Below will combine accompanying drawing and embodiment, the utility model will be carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the explosive view of the utility model.
Embodiment
Like Fig. 1, shown in Figure 2, a kind of slidingtype contacts little currents combination switch, comprises handle assembly 1; Slide block 3 with handle assembly 1 active link; Be installed in the contact bridge 4 on the slide block 3, have the pcb board 5 of circuit turn-on contact area, and support the shell 2 of pcb board 5 and slide block 3; Described contact bridge 4 is the contact bridge 4 of bending structure, also is provided with the convex closure that is used to connect circuit at the front end of contact bridge 4.The leading portion of contact bridge 4 is divided into 3, all has convex closure on each sheet.Described housing 2 is provided with the gathering sill of guide shoe 3 motions.
When stirring handle assembly 1; The slide block 3 that flexibly connects with handle assembly 1 moves along the gathering sill on the shell 2; The contact bridge 4 that drive is fixed on the slide block 3 moves together, bending structure on the contact bridge 4 and the convex closure that is arranged on contact bridge 4 front ends can make contact bridge 4 well with pcb board 5 on the circuit turn-on contact area overlap, this structure contact bridge 4 does not have plastic deformation simultaneously; Improved the useful life of contact bridge 4; And in whole motion process, do not have the power value that produced in other motion process, so all mild motions on pcb board 5 of contact bridge 4 in the whole motion process do not have the situation of sudden change; So operating handle can not receive the process motional effects, thereby reach the lifting of operating handle.
Claims (3)
1. a slidingtype contacts little currents combination switch; Comprise handle assembly,, be installed in the contact bridge on the slide block with the slide block of handle assembly active link; The pcb board that has the circuit turn-on contact area; And support the shell of pcb board and slide block, it is characterized in that: described contact bridge is the contact bridge of bending structure, also is provided with the protruding bubble that is used to connect circuit at the front end of contact bridge.
2. slidingtype as claimed in claim 1 contacts little currents combination switch, it is characterized in that: described housing is provided with the gathering sill of guide shoe motion.
